Background technique
Motorcycle is driven by gasoline engine, and by the two-wheeled or tricycle of bar handle front-wheel steer, light and flexible is travelled fast
Speed is widely used in patrol, passenger and freight transportation etc., also serves as sports movement apparatus.
Starting bar is the starting device of motorcycle.Motorcycle commonly starts there are two types of rod structures: two-link and monoblock type.
Starting bar is connect with start arm loop in two-link starting bar, and starting bar can be in start arm one angle of rotation, start arm big end
Hole is formed with spline (generally serration) and starting axis connection, while being formed with opening to clamp.Its feature is manufacturer
Just, but intensity is small, applies in general to discharge capacity in 100mL motorcycle below；Starting bar and start arm system in monoblock type starting bar
Integrally, lower part joint sleeve and starting axis connection, start arm can rotate an angle around joint sleeve.The starting bar of this form is strong
It spends, transferable torque is big, using more on the motorcycle of medium discharge capacity.
Existing spline fitting lock-screw hole drill hole tool is as shown in Figure 4: the spline tooth bottom outlet of spline fitting is covered in positioning column
On 10, spline rod is leaned against on column 9, is bored under drill bit, using the principle of three-point fix, guarantees that workpiece will not shift, to complete to produce
The processing of product, guarantees the quality of product, but lifts drill bit row when cut, and 3 points just lose a bit, when descending drill bit again,
Workpiece will shake displacement, the underproof phenomenon of the product that happens occasionally.
Utility model content
The purpose of this utility model is to provide a kind of motorcycle initiating bar spline fitting lock-screw hole drill hole tools, with solution
Certainly the problems mentioned above in the background art.
To achieve the above object, the utility model provides the following technical solutions:
A kind of motorcycle initiating bar spline fitting lock-screw hole drill hole tool, including tool assembly and cam, tool assembly installation
On the workbench of drilling machine, tool assembly pin is installed in the tool assembly, is also equipped in tool assembly and is slidably matched with it
The top of mandril, mandril is opposite with tool assembly pin, and cam is mounted in tool assembly, and the wheel face of cam and the bottom surface of mandril connect
Touching.
As a further solution of the present invention, the surface of the mandril be equipped with locating slot, locating slot be " V " shape or
" U " structure.
The cam is fixedly connected with handle as a further solution of the present invention,.
It is fixed with sliding sleeve in the tool assembly as a further solution of the present invention, mandril is embedded in sliding sleeve
And it is slidably matched with sliding sleeve.
Compared with prior art, the utility model has the beneficial effects that spline fitting can be always when drill bit downlink is with lifting
Held out against positioning, will not there is a situation where shake be displaced, worker can with opinion bore, technical requirements are not high, while also improving
The qualification rate of product.

Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all implementations consistent with this disclosure.On the contrary, they be only with it is such as appended
The example of device and method being described in detail in claims, some aspects disclosed in the present embodiment are consistent.
Embodiment 1
Please refer to Fig. 1~3, in the utility model embodiment, a kind of motorcycle initiating bar spline fitting lock-screw hole drilling
Tooling, including tool assembly 7 and cam 4, tool assembly 7 are mounted on the workbench of drilling machine, are equipped with tool assembly in the tool assembly 7
Pin 2, spline fitting can be mounted in tool assembly 7 by tool assembly pin 2, be also equipped in tool assembly 7 and be slidably matched with it
Mandril 3, the top of mandril 3 and tool assembly pin 2 are opposite, but in spline fitting clamping when on tool assembly pin 2, mandril 3
Surface be it is opposite with the bottom of spline fitting, cam 4 is mounted in tool assembly 7, and the bottom surface of the wheel face and mandril 3 of cam 4 connects
Touching, when cam 4 rotates, cam 4 can drive mandril 3 to move up and down, and when mandril 3 moves upwards, mandril 3 withstands spline fitting
Bottom, cooperation tool assembly pin 2 are able to achieve the good location to spline fitting.
Preferably, the surface of the mandril 3 is equipped with locating slot, locating slot is " V " shape or " U " structure, the table of mandril 3
When the bottom plane of face and spline fitting contacts, mandril 3 and tool assembly pin 2 are able to achieve three-point fix.
Embodiment 2
Please refer to Fig. 1~3, in the utility model embodiment, a kind of motorcycle initiating bar spline fitting lock-screw hole drilling
Tooling, on the basis of the above embodiments, band moving cam 4 rotates for convenience, and the cam 4 is fixedly connected with handle 5, rotates
Or when moving handle 5, the rotation of 5 energy band moving cam 4 of handle, certainly, when practical application, cam 4 can also be driven by motor, cylinder etc.
Turn is dynamic, herein also without specifically limiting.
Sliding sleeve 8 is fixed in the tool assembly 7, mandril 3 is embedded in sliding sleeve 8 and is slidably matched with sliding sleeve 8.Such mode
It is only the mode that one of mandril 3 is slidably matched with tool assembly 7, other modes can also be used.
In conjunction with the embodiments 1~2, it is apparent from the working principle of the technical program: the spline bottom outlet of spline fitting is covered in tool assembly
It above pin 2, is close to before tool assembly 7, swinging handle 5, handle 5 is rotated with moving cam 4, and cam 4 drives mandril 3 to moving up
It is dynamic, the lower plane of spline fitting is withstood using the locating slot of mandril 3, while holding out against spline fitting, using tool assembly pin 2 center and
The locating slot of mandril 3 is held out against spline fitting (i.e. three-point fix principle), and the spline fitting that drill bit 6 is directed at preprocessing on spline fitting locks
Bottom outlet 1 can downlink drilling, when drill bit 6 above proposes chip removal, spline fitting is still held out against by tool assembly pin 2 and mandril 3, spline fitting
It will not move, such spline fitting will not all move in entire boring procedure.
It should be strongly noted that, when drill bit downlink is with lifting, spline fitting can be held out against always in the technical program
Positioning, will not be there is a situation where shaking to be displaced, and worker can bore with opinion, and technical requirements are not high, while also improving product
Qualification rate.
Those skilled in the art will readily occur to other realities of the disclosure after considering the disclosure at specification and embodiment
Apply scheme.This application is intended to cover any variations, uses, or adaptations of the disclosure, these modifications, purposes or suitable
The variation of answering property follows the general principles of this disclosure and including the undocumented common knowledge in the art of the disclosure or used
